COMBINED TILE AND SAGGAR.

To all whom it may concern:

Be it known that l, GEORGE E. VANcn, a citizen of the United States of America, residing in Springfield, in the county of Clark, in the State of Ohio, have invented a certain new and useful Improvement in Combined Tiles and Saggars, of which the following is a true and exact description, reference being had to the accompanying drawings, which form a part thereof.

My present invention relates to, and has for its object, to provide improvements in the apparatus used in the burning of pottery and like articles such as emery wheels.

More specifically, the object of the present invention is to provide a combined saggar and tile for inclosing and supporting articles of pottery, or like nature, during the burning operation, which is shaped like a box, open at one end and having the other end (the tile or bat portion) formed of sections separable from and adapted to be detachably interlocked with the side wall, or saggar portion proper, of the combined structure.

A combined saggar and tile structure formed in accordance with the present invention is well adapted to withstand the severe conditions of operation in which the heat to which the structure is subjected is apt to produce strains tending to distort and rupture the structure. By forming the end wall of the combined structure in sections, the tendency to injurious distortion and to rupture, not only in that portion of the structure but in the structure as a whole, is greatly reduced, and when any one part of the structure is renderedinoperative it can be replaced by another similar section without discarding the rest of the structure.

The various features of novelty which characterize my invention are pointed out with particularity in the claims annexed to and forming a part of this specification. For a better understanding of the invention, however, and the advantages possessed by it, reference may be had to the accompanying drawings and descriptive matter in which I have illustrated and described several of the numerous forms in which the invention may be embodied.

Of the drawings, Figure 1 is a plan view, and Fig. 2 a sectional elevation, of a bung or assembled stack of the combined tile and saggar structure constructed in accordance with one form of the present in- Specification of "Letters Patent.

Application filed March 2, 1910.

vention. Fig. 3 is a perspective view of a portion of the combined tile and saggar structure shown in Figs. 1 and 2-. Figs. 4, 5 and 6 are perspective views, similar to Fig. 3, but each showing a different form of construction. Fig. 7 is a perspective view illustrating the use of tile sections such as are shown in Fig. 4, with a saggar in the form of an unbroken ring. Fig. 8 is a perspective view of a combined tile and saggar structure generally like that shown in Figs. 1, 2 and 3, but having an unbroken ring like saggar portion, and Fig. 9 is a plan view of a tile and saggar structure of oval cross sec tion.

In the drawings, and referring first to the construction shown in Figs. 1, 2 and 3, each combined tile and saggar comprises a ring like saggar portion formed of similar sections A, and an upper end wall, the major portion of which is formed of sections B. As shown, there are four each of the sections A and B. The saggar sections A are formed with internal ribs a which unite to form an annular supporting shelf for the end Wall or tile or bat sections B. Above the shelf formed by the shoulders a, grooves 64 are formed in the sections A, the grooves a uniting to form an annular channel or recess receiving the tongues Z) formed at the outer edges of the sections B. The sec tions B have their inner ends concaved at Z) and 6 so that when the parts are assembled a central aperture, having an enlarged outer end, is formed in the end wall of the combined tile and saggar structure. This aperture may be closed by a headed plug C when the parts are assembled as shown in Fig. 2.

It will be understood of course that the various portions of the combined tile and sag-gar may be formed of the material ordinarily used in making parts of this character, usually a mixture of fire clay and ground up fragments of old tiles and saggars.

When used in burning emery wheels, or the like, the combined saggars and tiles are stacked up as illustrated in Figs. 1 and 2. Each emery wheel D inclosed by a tile and saggar is placed on a bed E of quartz or the like, and is partially covered over by the same material. In assembling each tile and saggar, quartz is deposited on the support for the tile and saggar, the wheel D is then placed in position and the inclosing tile and saggar sections A and B therefor are put in place. The central opening formed in the inner ends of the sections B, B, is used in placing more quartz, it nee Irv, around the wheel, and in leveling oil the quartz, after wiich the headed plug C is put in place. It will of course be understood, as illustrated in Figs. 1 and 2, that the superimposed tile and saggar structure should be arranged to break joints. Each ring segment and the corresponding sector like end portion B, are interlocked so that the end portion cannot sag with respect to the portion, and the latter, on account of its curved shape, is firmly held in the proper position by the weight of the parts of the assembled bung supported by it. Each section A and the interlocked portion B, thus possess the same advantage of stability in the assembled bung which characterizes the structure disclosed and claimed in my urior application Serial No. 525,262, filed ()ctober 29, 1909.

In the structure illustrated in F ig. 4, the saggar portion of the combined structure is composed of sections A which unite to form a plain band or annulus, and the tile, or bat, sections 13 are formed each with a groove Z2 in its underside which fits over the top of the corresponding section A. To stifi'en the structure a rib 5* is formed on the underside of each section at the inner margin of the recess 6 which bears against the inner side of the section A.

In the structure shown in Fig. 5, the saggar sections A? are formed with an inturned flange a at their upper ends and with a channel a below the flange a receiving the rib 5* formed at the margin of each section B On the lower side of the inner end of the fiange a is formed a rib a which enters a recess Z2 formed in the rib Z2 of the sec tion B In the construction shown in Fig. 6 the saggar sections A have their upper edges thickened at a and received in undercut channels Z) formed in the underside of each of the tile sections B As in Figs. 1 and 5, the tile sections are formed with ribs 5 which bear against the inner wall of the saggar sections.

hen feasible, I prefer that the saggar should be formed in sections as hereinbet'ore described. The sectional saggar is open to the objection, however, that it may permit smoke to enter the interior of the structure. This is injurious in burning many articles of pottery, although such admission of smoke is of no importance in burning emery wheels and many like articles. When, in order to avoid the admission of smoke, or for other reasons, it is desirable to make the saggar portion of the combined structure in the form of an unbroken ring, it will be apparent that this can be easily done with thel mode of construction illustrated in Fig. at, and in Fig. 7 I have shown such an arrangement where A represents an unbroken saggar ring. It cannot be done, however, with out modification, with structures such as are shown in Figs. and 6 where the tile sections must be moved circumferential of the saggar sections in assembling, and this is true also of the construction shown in Figs. 1, 2 and 3. It will be apparent however that, as illustrated in Fig. 8, it tile sections B generally like the tile sections 13 of Figs. 1, 2 and 3, or some of them are arranged with overlapping shoulders 15 and B and with a slight provision for play at the joints B, such sections may be assembled in an integral saggar ring portion A shaped like the ring formed by assembling various sections A in the construction shown in Figs. 1, 2 and 3.

To assist in holding the assembled parts together, shoulders or ribs (4 and corresponding recesses a may be provided at the meeting surfaces of adjacent sections A, A, and the sections 13, B, may be provided with similar shoulders or ribs 6 and recesses Z9 as shown in Figs. 1, 2 and 3. This arrangement may be used of course with all the forms of the invention when a sectional saggar portion is employed, but is not necessary, and in generalis not feasible when the saggar portion is in one piece.

lVhile in the ordinary use of the invention the combination saggars and tile are usually circular in cross section, it is in some cases desirable to make them of other form. For instance they may be oval form as illustrated in Fig. 9 where 13 represents the tile sections.

It will be apparent to those skilled in the art that the formation of the tile or bat portions in sections separable from each other and from the saggar diminishes the liability of the tile sections breaking either in their body portions or at their junctions with the saggar portions. Individual parts, when broken or otherwise seriously damaged, may be replaced at small cost.

lVhile, in accordance with the provisions of the statutes, 1 have herein described and illustrated the best forms of my invention now known to me, it will be apparent to those skilled in the art that changes may be made in the form of the apparatus disclosed without departing from the spirit of my invention.

Having now described my invention, what I claim as new and desire to secure by Letters Patent, is:

1. A combined saggar and sectional tile structure for the purpose specified, comprising in combination with the saggar portion, tile sections detachably interlocked therewith.

2. A combined saggar and sectional tile structure for the purpose specified, comprising in combination with the saggar portion, sector like tile sections detachably interlocked therewith.

3. A combined saggar and sectional tile structure for the purpose specified, c01npris ing in combination a saggar portion, and de tuchable tile sections, said sections and saggnr portion being formed with interlocking i0 ribs and grooves.

l. A combined saggar and sectional tile structure for the purpose specified, comprising a saggar portion formed in segments and a tile portion formed in sector like sections, each saggar segment and a corresponding tile section being formed with interlocking ribs and grooves.
